Answer:
for your next answer it will be
Explanation:
2⁶(-4)
Answer:
The mile
Explanation:
this is calculated using the metric system in kilometers..
Answer:
Kinetic energy cannot be negative
potential energy is a reference dependent quantity and it can be positive as well as negative both
Since potential energy is defined only for conservative force so it can not be found for friction force
Explanation:
Kinetic energy of an object is given by the formula
here we know that
m = mass of object that can not be negative
v = speed of the object and since its square is given here so it can not be negative
so Kinetic energy is always positive
potential energy is given as the energy due to the virtue of the position of object
so it is
so potential energy is a reference dependent quantity and it can be positive as well as negative both
Since potential energy is defined only for conservative force so it can not be found for friction force
Answer:
W/16
Explanation:
The force of gravity, W = mg = GMm/R²
When R increases by a factor of four, W decreases by 4² or 16.
